Fix a crash in DataMerge_UpdateBindingRelations().

CXFA_Document::DataMerge_UpdateBindingRelations() expects a valid node
argument. Check all the callers and add checks to those that do not have
them.

For testing, add an alternative to xfa_object_2_0.fragment that makes it
easier to write all the XML in a single object.
